Nyjer seed (Thistle seed) is the absolute favorite of Finches, such as the American Goldfinch, Purple Finch, Pine Siskin, and other small Songbirds. This tiny delicacy is used in Finch feeders which have smaller holes and tiny perches-perfect for the Finches but discouraging to larger birds! Wagner's Nyjer seed is the ultimate choice for nurturing Finches with its high fat and protein content. Nyjer seed packs an incredible 150,000 seeds per pound and the seeds create no waste, no mess, no growth and produce more visits to your feeder. Fill your Finch feeder with Wagner's Nyjer seed and enjoy the antics of these beautiful and sociable birds in your backyard. Wagner's has been a trusted supplier of wild bird food for over 100 years.
